Convert PDF page to bitmap -> slow performances

Aspose.PDF Product Family

Hi all,

I am writing a small C# console application that exports the first page of a PDF document to Bitmap.
The code I use is pretty simple but it takes a reasonable time to complete even for small pdf files. Since it’s a real-time application launced to get a bitmap of a pdf file selected via a GUI, I need to understand whether it can be improved. Maybe the source code I used is too simple?!
Please have a look here:

                    doc = new Document(inputFile);

                    // create an object of bmpDevice
                    Aspose.Pdf.Devices.Resolution pageRes = new Aspose.Pdf.Devices.Resolution(72);

                    var renderer = new Aspose.Pdf.Devices.BmpDevice(Aspose.Pdf.PageSize.A4, pageRes);

                    renderer.Process(doc.Pages[1], outputFile);

Thank you for any help!
Kind regards,
Silvio

I measured the elapsed milliseconds and got almost 1900ms just for the “process” call function.
This is not good enough for us for a conversion on-the-fly of the first page.
